Does LED Light Therapy Really Work?

Those terrifying LED masks that haunt our dreams are here to stay (as much as we’d love to say otherwise). The reason? Light therapy is deemed safe for all skin types and tones and according to our chief dermatologist, it can help with certain acne symptoms. Cool, right? Let’s get into how it works.

 

How does light treatment help with acne?

LED (light emitting diode) lights use different wavelengths of light, including red and blue to penetrate the skin at different depths. This in turn triggers a biological effect to help the skin rejuvenate and heal.

 

What does red light do to the skin versus blue light?

Red light acts on cells called fibroblasts, which are responsible for collagen production. It can reduce inflammation and improve scarring and fine lines.

Blue light reduces the activity in the sebaceous (in other words: oil-producing) glands and kills acne bacteria. And you guessed it: less oil and bacteria = less acne.

 

Do LED light treatments damage the skin in any way? What about UV damage?

LED light therapy is deemed safe as it doesn’t contain UV rays and won’t cause burns. It’s suitable for all skin types and tones. Hurrah!

Is there a difference between professional and at-home LED treatments?

Home devices are usually less effective than professional treatments. So here’s your seal of approval — go ahead and book in with your favorite dermatologist or esthetician!

 

So, does it actually work?

Our chief dermatologist, Dr. Schaffran, says, “in practice, LED light treatment can be helpful but is not always enough on its own to treat significant acne.” Most people who use LED for acne will see some improvement, but it is best used in combination with other topical or oral acne medications.
